Ok just fired the game up to test it.

Right stick ---> Move
Up --> Spin Move
Left --> Swim Left
Right --> Swim Right
Down --> Bull Rush

If you are strong enough and the olinemen is weak you can flick Bull Rush right as you engage and just push in straight into the ground with a free path to the QB. On interior linemen I will engage then watch where the play is going then Swim to the side I need to to get free for the play. As DE I am on my Swims or Bull Rush as soon as the ball is snapped trying to get to the QB. If the OL has me held up and the Swim isn't working I try to Spin out.

EDIT: Also if you are engaged you can keep flicking down on the right stick to try and drive the olinemen back into the QB. Seems to gain much more ground then just using the left stick.
